如何在UITextView中自动换行？

Question

I have a UITextView contained within a UIScrollView. The UITextView is loaded dynamically depending on the UISegmentedControl, but I don't know how to word wrap it so the word moves to the next line.

.m:

@interface Tester ()
{
    UITextView *sponsor;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    sponsorInfo = [ [UITextView alloc] initWithFrame:self.sponsorsScrollView.frame];

    [sponsor setEditable:NO];
}

- (IBAction)control:(UISegmentedControl *)sender
{
    if (self.sponsorSegmentedControl.selectedSegmentIndex == 0)
    {
        [self changeGenericAbout:self.cellIndex];
    }
    else
    {
        //
    }
}

- (void)changeGenericAbout:(int)index
{
    if (index == 0)
    {
        sponsorInfo.text = @"[text in screen shot]";


        [sponsor sizeToFit];
        [self.sponsorsScrollView addSubview:sponsor];
    }
}

How can I achieve this word wrapping in iOS 7+?

First off I think your textview looks a bit strange. Shouldn't there be a margin on the right side as well? Now it sort of looks like the textview continues to the right. Are the frames correct or have you done something to the textContainerInset?

Anyway to answer your question regarding changing linebreaks: a textview's textContainer property has a lineBreakMode which could be set to NSLineBreakByWordWrapping. I think that should solve it
